CPU-Z is a freeware diagnostic tool, based on the Panopsys hardware detection engine, that provides information on your CPU, including: processor name and vendor, core stepping and process, processor package, internal and external clocks, clock multiplier, partial overclock detection, processor features, supported instructions sets, L1 and L2 cache information, location, size, speed, and technology.
CPU-Z also provides several tools: a complete report, that includes CPUID, MSR, PCI device list, SPD, DMI; a cache latency calculation tool.
This tool computes the real latency of each cache memory level. Notice that the reported sizes may not be the correct ones on CPUs that use an exclusive L2 (for example a Duron will report a 128Kb L2 cache size instead of 64Kb, because the L1 size in included).
Moreover, notice that using this tool if the CPUs is heavy loaded can provide bad results. Please use the “Refresh” button to restart the calculation.
What’s new in this version: AMD socket AM2/S1/F (rev F.) CPUs support, Enhanced Performance Profile (EPP) memory information report, Added Trc (bank cycle time) in DDR2 SPD report, added Trc (bank cycle time) on i925, i945, i955, i975 chipsets, FB-DIMM DDR2 SPD information report ..
